Occupants Restraint
Systems The listed occupants restraint systems
are some of the most important safety
features in your vehicle:
• Three-point seat belts (also called lap
and shoulder belts) for the driver
and all passengers.
• Front air bags for driver and
passenger.
• Seat-mounted side air bags for the
driver and front passenger.
• An energy-absorbing steering
column and steering wheel.
• Seat belts incorporate a pretensioner
(Emergency Tensioning Device - ETD)
that may enhance occupant
protection by managing the energy
created during an impact.
• All seat belt retractors are equipped
with load limiting devices which
control the seat belt reeling out so
as to adjust the force exerted on the
shoulders while the seat belt is in
restraining mode.
• All seat belts system (except the
driver’s) include Automatic Locking
Retractors (ALR), which lock the seat
belt webbing into position by
extending the belt all the way out and then adjusting the belt to the
desired length to restrain a child seat
or secure a large item in a seat.
Please pay close attention to the
information in this section. It tells you
how to use your restraint system
properly, to keep you and your
passengers as safe as possible.
If you are carrying children too small
for adult-sized seat belts, the seat
belts or the Lower Anchors and Tether
for CHildren (LATCH) feature also can
be used to hold infant and child
restraint systems. For more
information on LATCH, refer to
“Lower Anchors and Tether for
CHildren (LATCH)” in this section.
WARNING!
To help provide maximum protection,
you are advised to keep the seatback
in the most upright position possible
and the seat belt close to your chest
and pelvis. If the seat belt is loose, in
the event of an accident you could
move too far forward and could be
injured. Travelling with the seatback
too far reclined could also be
dangerous: even if the seat belts are
fastened, they may not work
correctly. In fact, the belt itself may
not be close enough to your body and, if it is in front of you, it could
cause neck wounds or other injuries in
an accident. Additionally, in an
accident, the lower section of the belt
could press against the upper part of
your stomach rather than the pelvic
area, causing serious internal injuries.
Here are some simple steps you can
take
to minimize the risk of harm
from a deploying air bag:
• Children 12 years old and under
should always ride buckled up in a
rear seat.
WARNING!
Infants in rear facing child restraints
should never ride in the front seat of
a vehicle with a passenger front air
bag. An air bag deployment can cause
severe or fatal injury to infants in that
position.
Do not use child seats or child booster
cushions/backrests in the front
passenger seat. Occupants in the front
passenger seat must never sit on the
edge of the seat, leaning toward the
dashboard or otherwise sit out of
position. The occupants’ back must be
as upright as comfort allows, and
must rest against the seatback with

• Never place or install floor mats or
other floor coverings in the vehicle
that cannot be properly secured to
prevent them from moving and
interfering with the pedals.
• Never put floor mats or other floor
coverings on top of already installed
floor mats. Additional floor mats
and other coverings will reduce the
size of the pedal area and interfere
with the pedals.
• Check mounting of mats on a
regular basis. Always properly
reinstall and secure floor mats that
have been removed for cleaning.
• Always make sure that objects
cannot fall into the driver footwell
while the vehicle is moving. Objects
can become trapped under the
brake pedal and accelerator pedal
causing a loss of vehicle control.
• Mounting posts must be properly
installed, if not equipped from the
factory. Failure to properly follow
floor mat installation or mounting
can cause interference with the
brake pedal and accelerator pedal
operation causing loss of control of
the vehicle. Tires
•
Examine tires for excessive tread
wear and uneven wear patterns.
• Check for stones, nails, glass, or
other objects lodged in the tread or
sidewall.
• Inspect the tread for cuts and cracks.
• Inspect sidewalls for cuts, cracks and
bulges.
• Check the wheel nuts for tightness.
• Check the tires (see “Tire Inflation
Pressure” chapter in section
“Features and Specifications”) for
proper cold inflation pressure.
Lights and Indicator Lights
• Have someone observe the
operation of exterior lights while
you operate the controls (see
“Lights” chapter in section
“Understanding the Vehicle”).
• Check turn signal and high beam
indicator lights on the instrument
cluster (see “Instrument Cluster”
chapter in section “Dashboard
Instruments and Controls”).
Door Latches
• Check for positive closing, latching,
and locking of doors and trunk lid
(see chapter “Doors” and “Open and
Close the Trunk Lid” in this section). Fluid Leaks
• Check area under vehicle after
overnight parking for recent fluid
leaks (oil, fuel, etc.).
• If gasoline fumes are detected or
fluid leaks are suspected, contact an
Authorized Maserati Dealer .

Tire and Loading Information Label
The proper cold tire inflation pressure
is listed on the driver's side rear door
pillar.
This label tells you important
information about the:
• Number of people that can be
carried in the vehicle.
• Total weight the vehicle can carry.
• Tire size designed for the vehicle.
• Cold tire inflation pressures for the
front, rear, and spare tires.
Loading
The vehicle maximum load on the tire
must not exceed the load carrying
capacity of the tire on your vehicle.
You will not exceed the tire's load
carrying capacity if you adhere to the
loading conditions, tire size, and cold
tire inflation pressures specified on the “Tire and Loading Information
Label” and in the “Features and
Specifications” section.
NOTE:
Under a maximum loaded vehicle
condition, gross axle weight ratings
(GAWRs) for the front and rear axles
must not be exceeded.
Tires
Driving over rough or damaged road
surfaces, as well as debris, curbs and
other obstacles can cause serious
damage to wheels, tires, and
suspension parts.
This is more likely to occur with
low-profile tires, which provide less
cushioning between the wheel and
the road.
Be careful to avoid road hazards and
reduce your speed, especially if your
vehicle is equipped with low profile
tires. WARNING!
Overloading of your tires is
dangerous. Overloading can cause tire
failure, affect vehicle handling, and
increase the stopping distance. Use
tires of the recommended load
capacity for your vehicle. Never
overload them.
Department of Transportation
Uniform Tire Quality Grades The following tire grading categories
were established by the National
Highway Traffic Safety Administration.
The specific grade rating assigned by
the tire's manufacturer in each
category is shown on the sidewall of
the tires on your vehicle. Driving

WARNING!
The wet performance (aquaplaning
resistance) will decrease
proportionally to the thickness of the
tread.
Tires Durability The service life of a tire depends on
various factors including, but not
limited to:
• driving style;
• tire pressure;
• distance driven.
WARNING!
Tires and the spare tire (if equipped)
should be replaced after six years,
regardless of the remaining tread.
Failure to follow this warning could
result in tire failure. Replacement Tires NOTE:
In order to maintain high performance
and safety level under all driving
conditions, Maserati strongly
recommends to use tires equivalent to
the originals in size, quality and
performance when replacement is
needed.
For the size designation of your tire
see the label on the driver's side rear
door pillar or see table “Wheels” in
section “Features and Specifications”.
The “Load Index” and “Speed Symbol”
for your tire will be found on the
original equipment tire sidewall.
It is recommended to replace the two
front tires or two rear tires as a pair.
Replacing just one tire can seriously
affect your vehicle’s handling.
If you ever replace a wheel assembly,
make sure that the wheel’s
specifications (valve, TPMS sensor and
tire) match those of the original
wheels. Failure to use equivalent
replacement tires may adversely affect
the safety, handling, and ride of your
vehicle.
Your Authorized Maserati Dealer is
available to provide suggestions as to the types of tires most suited to the
use foreseen by the Customer.
WARNING!
• Do not use a tire, wheel size or
rating other than that specified for
your vehicle. Some combinations of
unapproved tires and wheels may
change suspension dimensions and
performance characteristics,
resulting in altered steering,
handling, and braking operations of
the vehicle. This can cause
unpredictable handling and stress to
steering and suspension
components. Use only the tire and
wheel sizes with load ratings
appointed for your vehicle.
• Never use a tire with a smaller load
index or capacity, other than what
was originally equipped on your
vehicle. Using a tire with a smaller
load index could result in tire
overloading and failure.
• Always check the maximum speed
rating on the tire sidewall on any
tire on the vehicle.
• Never exceed the maximum speed
rating of the tires. Risk of accident
and serious personal injury due to
excessive speed.Driving

• Failure to equip your vehicle with
tires having adequate speed
capability can result in tire failure.
CAUTION!
Replacing original tires with tires of a
different size may result in false
speedometer and odometer readings.
Winter Tires These tires are specially designed for
driving on snow and ice and are fitted
to replace the ones supplied with the
vehicle. Winter or all-season tires can
be identified by the M+S (Mud &
Snow) or 3PMSF (3 Peaks Mountain
Snow Flake) designation on the tire
sidewall.
Before mounting winter tires, contact
an Authorized Maserati Dealer to
receive the technical information
necessary to advise you on wheel and
tire compatibility.
As to the type of tires to use, inflation
pressures and winter tires
specifications, carefully follow the
indications as reported in the
“Technical Data” and “Tire Inflation
Pressure” chapters in section “Features
and Specifications”. WARNING!
The standard tires profile and rubber
mixture are optimized for wet and dry
driving conditions. Standard tires may
not prove favorable for snow
conditions.
NOTE:
Snow
tires should have the same load
capacity as original equipment tires
and should be mounted on all four
wheels.
Snow Chains Maserati approved traction devices (or
snow chains) may be used to improve
traction on compacted snow in heavy
snow conditions.
The use of snow chains is specified by
local regulations of each country.
Use snow chains of reduced
dimensions, with a maximum
projection of 0.35 in (9 mm) beyond
the tire tread.
Maserati recommended to use snow
chains KONIG, type “Supermagic”.
The snow chains may be fitted only on
rear wheel tires.
Please, contact your Service for further
information. Check the snow chain tension after
driving for a distance of about 55 yd
(50 m) with the chains fitted.
With the snow chains fitted, it is
advisable to deactivate the ESC system
(see chapter “Drive Mode” in this
section).
CAUTION!
• The use of non-recommended snow
chains may damage the vehicle.
• Broken chains can cause serious
damage. Stop the vehicle
immediately if noise occurs that
could indicate chain breakage.
Remove the damaged parts of the
chain before further use.
• Do not exceed 30 mph (50 km/h).
• Drive cautiously and avoid severe
turns and large bumps, especially
with a loaded vehicle.
• Avoid holes in the road, do not drive
over steps or sidewalks and do not
drive on long stretches without
snow. This will prevent damage to
the vehicle and the roadbed. Driving

Tire Pressure Monitoring
System - TPMS Guidelines Each tire (including the spare tire, if
provided) should be checked monthly.
Tires should be checked when cold and
inflated to the inflation pressure
recommended by the vehicle
manufacturer indicated on tire
inflation pressure label (applied on the
driver's rear door pillar) and in “Tire
Inflation Pressure” of section “Features
and Specifications”.
If your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation
pressure label, you should determine
the proper tire inflation pressure for
those tires.
As an added safety feature,
your vehicle has been
equipped with a tire pressure
monitoring system (TPMS) that
illuminates a low tire pressure telltale
when one or more of your tires is
significantly under-inflated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure. Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to
tire failure. Under-inflation also
reduces fuel efficiency and tire tread
life, and may affect the vehicle’s
handling and stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the
level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated. This
sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists. When the
malfunction indicator is illuminated,
the system may not be able to detect
or signal low tire pressure as intended.
TPMS malfunctions may occur for a
variety of reasons, including the
installation of replacement or
alternate tires or wheels on the vehicleDriving
5
184

that prevent the TPMS from
functioning properly. Always check the
TPMS malfunction telltale after
replacing one or more tires or wheels
on your vehicle to ensure that the
replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.
General Information The Tire Pressure Monitoring System
(TPMS) will warn the driver of a low
tire pressure according to the vehicle
recommended cold pressure indicated
on the table “Tire Inflation Pressure”
in section “Features and
Specifications” and on the label
applied on the driver's side at the base
of the rear door pillar.
The cold tire inflation pressure must
not exceed the maximum inflation
pressure molded into the tire sidewall.
Check “Tires – General Information” in
section “Driving” for information on
how to properly inflate the tires.
The tire pressure will also increase as
the vehicle is driven - this is normal
and there is no adjustment required
when this occurs.
The TPMS will warn the driver of a low
tire pressure if the tire pressure falls
below the low-pressure warning limit
for any reason, including low temperature effects and natural
pressure loss of the tire.
The TPMS will continue to warn the
driver of low tire pressure as long as
the condition persists and will not turn
off until the tire pressure is equal or
above the recommended cold
inflation pressure.
The TPMS monitors the tire pressure
by means of special sensors fitted
inside the wheel rims, in position with
the inflation valve.
These sensors transmit a signal that is
detected by the antenna integrated in
the ECU.
The ECU processes this information
and, via the CAN line, transmits a
series of tire pressure data and system
errors, if any, to the instrument cluster.
The display may show the information
received by means of specific screen
pages, which can be recalled by
pressing briefly the "MODE" button
(see "TFT Display: Controls" in chapter
"Instrument Cluster" of the section
Dashboard Instruments and
Controls"). WARNING!
The TPMS warns the driver that the
tire pressure has decreased. This
warning does not exempt the driver
from periodically checking the tires
and from complying with the
prescribed tire pressure levels.
CAUTION!
• The TPMS has been optimized for
the original equipment tires and
wheels. TPMS pressures and warning
have been established for the tire
size equipped on your vehicle.
Undesirable system operation or
sensor damage may occur when
using replacement equipment that is
not of the same size, type, and/or
